Using nsupdate to update a DNS server using docker

Summary This sets up a continual check (using cron) to obtain the current external IP, and if it has changed from the last check, update the remote dns server (that you need full access to). Notes do not as yet show how to set up the dns server and certs. Suggestions for simplifying welcome, maybe holding the current IP address...

Smartphone screen protector UV cured

I have had various phone screen protectors over the years, floppy and solid and preferred the solid glass cover I had on on my Note 8 for over a year I paid NZ$30+ for the last one including install by someone at a ‘phone shop’ but really it wasn’t a nice install, and I re-seated it not long to try...

Tasmota Energy Meter Pulse Output Counting

Summary This monitoring was built as part of my whole house 3 phase monitoring project. I had a couple of kWh counters (often called Check Meters) on my main and a sub board. Not as accurate, and can’t monitor V or power factor etc, but useful to look at targeted areas of power use as well as having their own...

Whole House Surge Suppression for 3 Phase

Summary Common in Europe and other locations around the world, but not really in NZ is the use of surge suppression modules in a main DB. I have a few servers and sensitive equipment so thought it might be a good idea as I was building a small power monitoring switchboard anyway. Standard install practice is to use an MCB...

Whole House 3 Phase Power with PZEM-004T

A robust, accurate, low cost and safe whole house electricity monitoring setup, using PZEM-004T modules. These use current transformers (CTs), and send data as TTL Modbus-RTU. Recently Tasmota has added support for up to 3 of these directly (on the same data channel) so there are fewer hoops to jump though to get them working (previously my testing involved sending serial commands)

Secure the Chocolate: Simple Cupboard Security

We have created a self contained area of our house that we still use a lot ourselves, and part of the need is to be able to store and use spaces for our own stuff… without guests having access. One of the bedrooms and a full sized cupboard can be locked with a key when needed, but what do you...

Use of a Low cost WH1080 USB Weather station, connected by USB to an intel NUC running docker.
Weewx pushes data to a local MQTT server (on the same NUC) and also uses SFTP to push graphs and displays to my commercial webserver.

Sinilink USB XY-WFUSB Tasmota Flash

Summary Pics and notes for flashing a Sinilink USB Stick XY-WFUSB with Tasmota This is a USB A Male to female stick, with an esp8266 in it to switch the output. It can be flashed with Tasmota, but has annoyingly small 1.27mm pitch headers. I used the ‘sewing pin’ method suggested in a couple of places. If I was doing...

Large TV Recessed Mounting

This was a setup in our rumpus room to house a TV. I made the recess etc probably 8 months before I even thought about getting a TV for it, and I sort of ‘estimated’ the size I’d need. The back of the recess is 12mm MDF and it is set 100mm back from the Gib. There was heaps of room behind this wall due to how this area under the house is constructed. Using a sheet of MDF meant I didn’t need to worry about what I was going to do with a TV bracket later – it could be screwed anywhere.

Over Stair TV Cabinet + Hall Storage

Because I hate unused space… I decided to plan a storage unit for above where our stairs go from our lounge to the lower level. There is decent ceiling height here, and the back of the area is accessible from the hallway. We thought of the concept when we were renovating the hall about 12 months previous, and so cut...

Home Automation: Future Thinking

So, home control with your own setup is great, but you have to think about what happens in the event you sell your house, get hit by a bus or someone needs to work on it in the future. Home Automation should add value to a house, not turn people off a sale. This is part 2 of some of...

Home Automation: Electrical Safety

This is part one of some of my notes regarding Home Automation concepts. Part 2 is about planning for the future and house resale value. Electrical Isolation/Safety Electrical safety is very important obviously for home automation, and as well as my tendency to over-engineer, I’m often thinking about ‘what could possibly go wrong‘. One of the things I want to...

How much do you save buying a used EV, and is it worth it? How long is the payback? This is the story of my original conservative payback estimates for buying a Nissan Leaf, but plot twist… the actuals are much, much better.

Conversion of Ceiling Attic to Storage

In 2019 I converted a ceiling space atticin our current house to storage (on a budget). You can never have enough home storage. This is the 5th type of install I’ve done like this (Similar in 4 previous houses), and as well as being useful, home buyers love it (if done well).

Lachco Front Door Lock for Home Automation

I researched, bought and installed an electronic front door lock to go with the home automation & security system for under NZ$200 in 2017. I looked for one with these features specifically as it was a free egress handle, would lock on door close (not a deadlock) and had a wireless RF remote… which is an easy way to connect...

Whole House Audio on the Cheap

You can pay thousands for Bose multiroom audio systems, or buy a huge stereo and crank it up so you can hear it throughout the place. You can also get multiple digital distribution amplifiers that run over Wifi (eg Sonos), but again they come at a huge cost. What you really want though is cheap DIY multiroom background music system....

Dog Motel

We just got a new and decided it needed a place to hang out outside… and somewhere to poop as we had no grass area. The area was an existing pebble garden that we cleared and put down a scoria base. We built a picket fence around the edge and laid some astroturf. The gate will mainly remain open as...
